Abstract

The communication device includes a transmitter for transmitting communication signals through a transmitter output terminal, a receiver for receiving communication signals through a receiver input terminal, and a coupling unit for coupling the transmitter output terminal and the receiver input terminal to the shared transmission medium, and including a first filter for passing communication signals from/to the shared transmission medium within a first communication frequency range, and a second filter for passing communication signals from/to the shared transmission medium within a second communication frequency range disjoint from the first communication frequency range.

First claim

The invention claimed is:

1. A method for assigning communication resources to a plurality of communication devices for communication over a shared transmission medium, the method comprising:
assigning first frequency carriers in a first communication frequency range for downstream communication and second frequency carriers in a second communication frequency range disjoint from the first frequency range for upstream communication to a first part of the plurality of communication devices, and assigning the second frequency carriers for downstream communication and the first frequency carriers for upstream communication to a second part of the plurality of communication devices; and
in response to a first communication device and a second communication device out of the plurality of communication devices have been characterized as highly-interfering communication devices, assigning the first and second communication devices to the same one of the first part or the second part of the communication devices.

2. A method according to claim 1 , wherein
the method comprises assigning third pre-determined frequency carriers in the first and second communication frequency ranges for establishment of a basic communication channel with respective ones of the plurality of communication devices, and
configuration information is conveyed over the basic communication channel for configuring respective ones of the plurality of communication devices as belonging to the first or second part of the communication devices.

3. A communication controller for assigning communication resources according claim 1 to a plurality of communication devices for communication over a shared transmission medium.

4. An access node comprising a communication controller according to claim 3 .
